The Symbian Image Converter Library (ICL) supports the decoding of image files. You can use the ICL architecture to load an image stored in a file or a descriptor and convert it to a CFbsBitmap object. Use this bitmap object, for example, to display the image on the screen of the mobile device after the capture.
To convert an image to display it on the screen of the device:
Use the methods of the CImageDecoder (or CBufferedImageDecoder) class to construct your application.
Create a CImageDecoder object using CImageDecoder::DataNewL() (for descriptor) or CImageDecoder::FileNewL() (for file) method.
Select a suitable plugin for the actual decoding. For a list of available plugins, see the Symbian OS Library.
Request information about the image using, for example, CImageDecoder::FrameInfo() and CImageDecoder::FrameCount().
Decode the image using the CImageDecoder::Convert() method.
Include ImageConversion.h and Fbs.h header
files in the appropriate class file(s).
Make sure
you have correct capabilities information
set for your application. You need at least the ReadUserData capability.
Make sure imageconversion.lib, bafl.lib, fbscli.lib and efsrv.lib are accessible to your
linker when compiling your application by including them in your mmp file
or by editing the project properties in your IDE, depending on your build
environment.
